Inotrope, vasopressors, and vasocontrictors Flashcards
What are the actions of epinephrine?
Relaxes beta 2, vasoontricts, increaeses HR, loser dose causes vasodilation
What are the actions of dopamine (inotropin)?
Increase cardiac output
Why might dopamine (inotropin) be ordered for a patient?
Correct CO, decrease BP, improve perfusion, and correct hemodynamics.
List the nursing implications for dobutamine (dobutrex)?
- Monitor vital signs
- correct electrolyte imbalances
- CO/CI
- BP
Actions of phenylephrine (Neo-Synephrine)
Direct acting powerful al[ha agonist, arterial vasocontriction, and increases BP
Major side effects of phenylephrine?
- EKG changes
- decreases HR
- Dysrhythmias
- decreased CO
- tissue necrosis
Pure inotrope that might be ordered to treat HF?
Dobutamine hydrochloride
How can epinephrine affect blood sugar?
Increase the blood sugar
What is the dose we give of epinephrine during cardiac arrest?
1mg
First line medication for septic shock?
Norepinephrine
Response expected from low dose vasopressors?
Vasodilation
Response expected from high dose vasopressors?
Vasoconstriction
What does it mean when a vasopressor has inotropic support?
Increase in CO and HR.
Name an alpha-adrenergic vasoconstrictor medication discussed in class?
Phenylephrine
